Add Lua version of the script to autoinstall missing plugins

[ac1dTigR]

Description

I propose that this code snippet be added to the Tips page on the wiki:

-- Run PlugInstall if there are missing plugins
vim.api.nvim_create_autocmd("VimEnter", {
  callback = function()
    local plugs = vim.g.plugs or {}
    for _, plug in pairs(plugs) do
      if vim.fn.isdirectory(plug.dir) == 0 then
        vim.cmd("PlugInstall --sync")
        vim.cmd("source $MYVIMRC")
        break
      end
    end
  end,
})

Note: the code was generated by ChatGPT (https://chatgpt.com/s/t_6a51a66c67fc8191a0037a87aa6e7ad3) and tested by me.
